My friend has one, the thing is super fast! When he can harness the bow, he hits the center of the X like I have never seen, but usually he can't group very well. I tried it and I could not group at all with it. I just bought the Guardian from Bowtech and I am kicking butt over my friend that has the X-force.
Yesterday I shot the 80 yard target for the first time with my new bow. I never hit the bullseye at 80 with my old bow. The first 3 arrows, I hit one bullseye, with one right, and one left. Second try, I shot 4 arrows, 2 of which were bullseye's and 2 where touching the edge of the bullseye.
Only one way to get there, it's in the middle of no where, you gotta get a little mud on the tires.
Correction! Used to have to get a litlle mud on the tires!
